The Hydrogen Economy

Fossil fuels like coal, oil, and gas power most of the world today, but burning them releases carbon dioxide, which traps heat and drives climate change — melting polar ice, raising sea levels, and threatening coastal nations. To avoid this, we must shift to a cleaner energy source. Hydrogen is an ideal alternative because its combustion yields only water, and if produced by splitting water using solar energy, it becomes a renewable, non-polluting fuel — this is the vision of the Hydrogen Economy. Both the production of hydrogen (via electrolysis of water) and i …
